Specifications
General Information
| Parameter | Value |
|---|---|
| Product Name | NA-65H |
| Product Type | Polyolefin nucleating agent (alpha, stiffness-enhancing) |
| Target Polymer | Polypropylene (homopolymer and copolymer) |
| Manufacturer | Zhejiang Bastone Technology Co., Ltd |
| Production Site | Hangzhou Economic Development Zone, China |
| Physical Form | Powder |
| Food Contact | Non-migrating; suitable for food-contact applications |
Technical Properties
Comparative performance in polypropylene, NA-65H versus imported NA-11, both at 0.1% loading:
| Property | Unit | 0.1% NA-65H | 0.1% Imported NA-11 |
|---|---|---|---|
| Flexural Modulus | MPa | ~1,900–1,950 | ~1,750–1,800 |
| Flexural Strength | MPa | ~50–51 | ~46–47 |
| Crystallization Temperature (Tc) | °C | ~128.5 | ~127 |
Values reflect BASTONE comparative test data on a single PP matrix at matched loading. Performance in a specific resin depends on base polymer grade, MFR, and compounding conditions — request a trial evaluation for your own formulation.
Recommended Processing Conditions
| Parameter | Recommendation |
|---|---|
| Addition Level | 0.05%–0.30% by weight (adjust to application requirements) |
| Mixing Method | High-speed blending with PP powder or pellets before extruder feeding |
| Dispersion Aid | Small addition of white mineral oil during high-speed mixing to bind powder to resin |
| Alternative Addition | Prepare as a high-concentration masterbatch, then dilute to target loading |
| Extrusion Equipment | Twin-screw extruder, or single-screw with high-intensity mixing capability |
| Extrusion Temperature | Standard PP processing parameters — no significant adjustment required |
| Processing Methods | Extrusion, injection molding, compression molding |
Dispersion quality drives nucleation efficiency. Uneven feeding or poor distribution costs mechanical performance, which is why BASTONE recommends twin-screw compounding or masterbatch dilution over direct dry blending into low-shear equipment.
Applications
Washing machines and small appliances. Appliance structural parts carry load and sit near heat sources. The flexural modulus increase from NA-65H lets molders hold rigidity in drum surrounds, housings, and internal brackets, while the higher heat distortion temperature keeps parts dimensionally stable through wash and dry cycles.
Automotive modified polypropylene. Compounders formulating PP for interior trim, under-hood components, and structural parts use NA-65H to raise stiffness without additional mineral filler. Holding modulus while reducing filler content keeps part weight down and preserves impact performance — the stiffness/toughness balance NA-65H is built around.
Electrical and electronic components. Housings, connectors, and enclosures need dimensional stability at elevated service temperature and a clean surface finish. Higher Tc improves molded-in dimensional consistency, and the gloss improvement removes a secondary finishing step on visible parts.
Plastic bottle caps and closures. Closure molding runs high-cavitation tools where cycle time governs plant economics. Accelerated crystallization lets the part eject sooner, and the non-migrating character of NA-65H supports beverage and food packaging closures where extractables are regulated.
General consumer plastics. Housewares, containers, and everyday molded goods benefit from the combined package — faster cycles, better stiffness, improved transparency and gloss at loadings as low as 0.05%.
Why Choose BASTONE
BASTONE manufactures NA-65H, rather than reselling it. Production runs at BASTONE's own Hangzhou Economic Development Zone facility under BASTONE's proprietary formulation, which means the specification you qualify is the specification BASTONE controls — raw material selection, reaction conditions, particle sizing, and release testing all sit inside one organization.
Technical depth comes from the group structure. BASTONE operates 4 production sites and 1 R&D center, staffed by chemists who develop additive formulations rather than simply repackaging them. When a customer's PP grade responds differently than expected, BASTONE's lab can run the DSC and flexural work to diagnose it and adjust loading recommendations — support a trading house cannot provide.
Buying direct from the producer removes the distributor margin from the landed cost, and BASTONE quotes export pricing at the factory level. The export platform Zhejiang Bastone Technology Co., Ltd handles trade terms, documentation, and shipping coordination, with 10+ years of export experience behind the paperwork. BASTONE Petrochem's broader portfolio — organic and inorganic chemicals, polymers, fuel additives, drilling chemicals — lets compounders consolidate multiple additive and raw material lines under one supplier and one set of shipping documents.
